Hello team,
I was doing the frame-relay lab-workbook1 and encountered the below issue.
The question is to configure the frame-relay on R1, R2, R3, R4 and R5 according to the INE diagram where as R1& R2 are in the subnet 155.X.100.x and R3& R4 are in the subnet 155.X.200.x
R5 should have it's main interface configured for frame-relay and 2 sub interfaces .100& .200 configured for R1, R2 and R3, R4 respectively
R1, R2, R3& R4 should have rechablity to R5 but not each other and configure them in a way that they will not send inverse-arp req for the ip out any DLCIs learned from the frame-relay cloud other than those in the diagram.
When i did the lab, everything worked well, but i got 2 replies from R5 when I send a broadcast request (repeat count 1). Got the same issue on R3 as well. R2& R4 worked pretty good and got only one response. Please check the below config and advise if you see any issues in the configuration.
